Inria Chile continues its development in South America. In recent years, with Claude Puech at the helm, she has strengthened her network of contacts and has set up partnerships with investment structures to accelerate the creation of strategies in Chile. Appointed on September 1st as Director, Nayat Sanchez Pi intends to pursue this strategy and implement an ambitious settlement project that includes opening to French partners, the revitalization of the transfer policy and the establishment of a sustainable economic model.

Thirty years ago, the Web was set up to meet an ever-growing need to organise and access information. As a founding member for Europe of the W3C, Inria take a look back at the birth of the Web as both a research subject and a tool, assessing the problems that continue to be raised.

Capitalizing on five years of research-collaboration success, Mitacs and Inria renewed their partnership originally signed in 2014. The memorandum of understanding (MOU) supports two-way international research opportunities for graduate researchers at Canadian universities and at eight Inria Research Centres in France.

The CNIL (French Data Protection Authority) and Inria have awarded the 2017 "privacy protection" Prize to a European research team. During the 11th international conference Computers Privacy and Data Protection
(CPDP) to Seda GÜRSES, Carmela TRONCOSO and Claudia DIAZ for their article « Engineering privacy by design reloaded

The CCSD (Centre for Direct Scientific Communication) and Software Heritage have announced their collaboration beginning early 2018: it will enable the data repository in HAL to be extended to software and, as a result, contribute to the recognition of the work of research software developers.

Facebook is investing an additional 10 million Euros and doubling the Facebook AI Research (FAIR) team in order to accelerate research on artificial intelligence in France. As a result, Facebook's European hub is strengthening its partnership with Inria.

InriaSoft aims for the durable development of large-scale software programs by bringing together their user communities within consortia that will finance a team of engineers tasked with their maintenance and evolution. The InriaSoft headquarters are based in Rennes, as Claude Labit, director, and David Margery, technical director of this national action backed by the Fondation Inria, explain.

Gradual Parametricity, Revisited

Bringing the benefits of gradual typing to a language with parametric polymorphism like System F, while preserving relational parametricity, has proven extremely challenging: first attempts were formulated a decade ago, and several recent developments have been published in the past year.

In addition to leaving some properties as conjectures or future work, we observe that all prior work improperly handle type instantiations when imprecise types are involved. This observation further suggests that existing polymorphic cast calculi are not well suited for supporting a gradual counterpart of System F.
Consequently, we revisit the challenge of designing a gradual language with explicit parametric polymorphism, exploring the extent to which the Abstracting Gradual Typing methodology helps us derive such a language, GSF. We present the design and metatheory of GSF. In addition to avoiding the uncovered semantic issues, GSF satisfies all the expected properties of a gradual parametric language, save for one property: the dynamic gradual guarantee, which was left as conjecture in all prior work, is here proven to be simply incompatible with parametricity. We nevertheless establish a weaker property that allows us to disprove several claims about gradual free theorems, clarifying the kind ofreasoning supported by gradual parametricity.
